Nanofluid minimum quantity lubrication grinding device of ultrasonic vibration assisted grinding fluid micro-channel infiltration

An ultrasonic vibration mechanism capable of adjusting a spatial position of ultrasonic vibrators, comprising:

• an arc track base with an arc track at a top;
• an adjustable rotor, the bottom of which is arranged on the arc track, wherein the adjustable rotor can rotate along the arc track;
• a first ultrasonic vibration component, arranged in a center of the adjustable rotor;
• a second ultrasonic vibration component, arranged above a surface of the adjustable rotor through a holder, wherein the second ultrasonic vibration component is parallel to an upper surface of the adjustable rotor, and the second ultrasonic vibration component is arranged perpendicular to the first ultrasonic vibration component;
• and
• a workpiece fixing table, a bottom of which is in contact with or connected to the first ultrasonic vibration component and the second ultrasonic vibration component to transmit ultrasonic vibration to a workpiece,
• wherein an ultrasonic tool head is arranged at the bottom of the workpiece fixing table, the ultrasonic tool head is fastened to the first ultrasonic vibration component and the second ultrasonic vibration component respectively, a top of the ultrasonic tool head forms an arc surface, and T-shaped groove tracks are formed in the arc surface,
• wherein the arc track and a cylindrical surface where the arc surface formed by the ultrasonic tool head is located are concentric cylindrical surfaces, and
• wherein vibration directions of the first ultrasonic vibration component and of the second ultrasonic vibration component are configured to be changeable along a vertical plane.
